CALCIUM (AS CALCIUM OXIDE) CALCIUM CONTENT 69%

Calcium oxide, a highly concentrated source of elemental calcium, is widely utilized in the supplement industry for its exceptional purity and efficacy. Derived primarily from the calcination of naturally occurring limestone deposits, it presents as a fine, white, odorless powder. With an impressive elemental calcium content of approximately 69%, calcium oxide offers a significant advantage in formulation, allowing for smaller serving sizes to achieve desired daily value targets compared to other calcium salts. This makes it a cost-effective and space-efficient ingredient for various dietary supplements. Its robust chemical stability ensures a long shelf-life and consistent potency, critical attributes for high-quality nutritional products. Understanding its origin and inherent characteristics is fundamental to appreciating its role as a foundational mineral ingredient.

The primary health benefits associated with calcium intake, delivered effectively by calcium oxide, revolve around its crucial role in skeletal health, nerve transmission, and muscle function. Calcium is the most abundant mineral in the human body, with over 99% stored in bones and teeth as hydroxyapatite, providing structural integrity. Beyond bone mineralization, calcium ions act as vital intracellular messengers, regulating processes such as muscle contraction, neurotransmitter release, and hormone secretion. Scientific research, including numerous meta-analyses and clinical trials, consistently demonstrates that adequate calcium intake is essential for maintaining bone mineral density and reducing the risk of osteoporosis, particularly in aging populations. For instance, a review published in the *British Medical Journal* highlighted the importance of dietary calcium for fracture prevention, underscoring its broad physiological significance.

Calcium oxide is frequently incorporated into various supplement formulations, including tablets, capsules, and powdered drink mixes, due to its high elemental load. When formulating, considerations for bioavailability are important; calcium oxide requires sufficient stomach acid for dissolution and absorption, a factor often addressed by combining it with ingredients that support digestion or by recommending intake with meals. Quality assurance for calcium oxide involves rigorous testing for heavy metals and other contaminants, ensuring compliance with strict regulatory standards. Extensive scientific evidence supports calcium's role in public health, with organizations like the National Osteoporosis Foundation and the European Food Safety Authority (EFSA) recognizing its benefits for bone health across all life stages. Ongoing research continues to explore calcium's nuanced interactions with other nutrients, such as Vitamin D, to optimize its systemic effects and overall health impact.
